This document outlines a lesson plan to teach students addition through counting groups of objects. The lesson begins by introducing classroom puppets and counting how many each student holds, then combining the groups. Stories are used to present addition word problems using cut-out objects like teddy bears. Finally, students practice combining Unifix blocks in groups, counting each group and the total, and creating their own addition stories up to 10. The goal is for students to understand and represent addition as combining groups and counting all items.
